Fed Rate Expectations Explained: How to Read the Odds

When a trader says the market is pricing a 70% chance of a cut, that number is not a survey or a guess. It is extracted directly from the price of 30-Day Fed Funds futures. Understanding where it comes from tells you not just the odds, but when they are about to move — which is what actually trades.

From futures price to implied rate

30-Day Fed Funds futures settle to 100 minus the average effective fed funds rate for the contract month. So if the August contract trades at 96.38, the market expects an average rate of 3.62% in August. Compare the contract for a month before an FOMC meeting with the month after, and the difference tells you exactly how much easing or tightening is priced in.

From implied rate to probability

The Fed moves in 25 basis-point steps. If futures price 10bp of easing at a meeting, the market is effectively saying there is a 40% chance of a 25bp cut and a 60% chance of a hold, because 0.4 × 25bp = 10bp. That simple conversion — the same one CME's FedWatch tool uses — turns a futures price into the hike / hold / cut odds you see quoted everywhere.

How to trade around a decision

• When odds sit near certainty (90%+), the decision itself is usually a non-event — the reaction comes from the statement and the press conference, not the number.
• The biggest moves come from surprises against heavily priced outcomes. A hold when the market priced a near-certain cut is where the volatility lives.
• Ahead of FOMC days, expect position squaring, wider spreads, and prop-firm news-trading restrictions around the 2:00 PM ET release.

The rate path, not just the next meeting

Traders who only watch the next meeting miss the bigger signal: the implied rate path. Chaining the implied rate across the next several meetings shows the market's expected trajectory — and when that whole curve shifts, rate-sensitive assets reprice together. That is the difference between reacting to one decision and positioning for a cycle.
